Abstract:
Objective:To compare the clinical outcomes of capsular closure versus those of non-closure in hip arthroscopy for femoroacetabular impingement (FAI) through a meta-analysis of randomized controlled trials (RCTs).Methods:A systematic search was conducted in Cochrane Library, PubMed, Web of Science, China National Knowledge Infrastructure (CNKI), and Wanfang Database for RCTs comparing capsular closure with non-closure in hip arthroscopy for FAI, covering the period from database inception to October 2024. A meta-analysis was performed using RevMan 5.3 software to compare outcomes between patients undergoing hip arthroscopy with capsular closure versus those without capsular closure within 2 years postoperatively. The following parameters were evaluated: the modified Harris hip score (mHHS), 12-item International Hip Outcome Tool (iHOT-12), hip outcome score-activities of daily living (HOS-ADL), hip outcome score-sport specific (HOS-SSS), Copenhagen hip and groin outcome score (HAGOS), visual analog scale (VAS) for pain, reoperation rate, complication rate, and rate of patient satisfaction.Results:A total of 5 RCTs involving 432 patients were included, with 215 cases in the capsular closure group and 217 cases in the non-closure group. The follow-up duration for the patients in the included studies ranged from 12 to 24 months. Meta-analysis revealed no significant differences between the capsular closure and non-closure groups in postoperative functional scores (mHHS, iHOT-12, HOS-SSS, HAGOS), VAS pain score, reoperation rate, complication rate, or rate of patient satisfaction ( P>0.05). The capsular closure group demonstrated significantly better HOS-ADL at 2 years postoperatively than the non-closure group (MD=-3.57, 95% CI: -5.86 to -1.28, P=0.002). Conclusion:In patients with FAI undergoing hip arthroscopy, compared to the non-closure, capsular closure leads to significant improvements in mid-term daily activities, but similar outcomes in short-term hip function, pain control, reoperation rate, and complication incidence.
